Materials
Ferrocerium: Our fire starting tools utilise a proprietary alloy of
rare earth metals called ferrocerium. Some of these metals
include Iron, Cerium and Magnesium. When a ferrocerium rod is
rapidly scraped, the friction created ignites the shavings producing
molten globulars of burning metal. It is these long-burning
molten globulars of metal that make a ferrocerium fire starter so
effective at catching other materials afire.

Usage
To replace an old rod, simply unscrew the rod and screw in the new
rod. Ensure the rod is a snug fit into the rod holder. An
optional drop of blue or purple loctite will help retain the rod if it
becomes loose.
